Someone do as much of the page as possible (ill mark brainlyless)

Sindrei [870]

Answer:

Step-by-step explanation:

1) a² - b² = (a + b)(a- b)

2) a³ + b³ = a³ + 3a²b + 3ab² + b³

3) a³ - b³ = a³ - 3a²b + 3ab² - b³

5) x⁴ - 36 = (x²)² - 6² = (x² + 6) (x² - 6)

6)64c³ + 1 = (4c)³ + 1³ = (4c)³ + 3(4c)²(1) + 3(4c)(1)³ + 1³

= 64c³ + 3(16c²) + 12c +1

= 64c³ + 48c² +12c + 1

7) k³ - 27 = k³- 3³ = (k + 3)(k - 3)

3-X²=-7 How do I solve

irga5000 [103]

Answer:

x = 3.162

Step-by-step explanation:

Your first step is to get x by itself by subtracting 3 from both sides.

3- $x^{2}$ = -7

- $x^{2}$ = -10

Now multiply by both sidex by -1 to make x positive.

$x^{2}$ = 10

now take the square root of both sides.

$\sqrt {x^{2}$ = $\sqrt{10}$

x = $\sqrt{10}$

x = 3.162
